Title: Improvements in or relating to Pneumatic Tyres.
Filed: 1899-10-19
Granted: 1900-10-13
Abstract: 20,953. Dessau, M. M., and Wapshare Tube Co. Oct. 19. Tyres, pneumatic.-Relates to wire fastenings for tyres such as are described in Specification No. 19,502, A.D. 1897. Each end of the wire at both sides of the tyre is secured to a tag B, the folds of which are cemented together and to the cover with the ends of the wire overlapping. The tag i s secured by folding it over the wire A and a screw-threaded sleeve C, loose on the wire but unable to slip off on account of a bead D held by the rivet head A'. The folds are fixed, preferably sewn, to the sleeve and wired as indicated at B'. The wire and overlapping parts are covered with loosely-woven material E. Details of construction may be somewhat modified ; thus, the sleeve C may be swivelled to the end of the wire.

Granted: 1899-12-09
Abstract: 21,970. Appen, H. von. Nov. 2. Pipe cutters; cutters.-The tool is for cutting through the tubes used for protecting and insulating electric conductors and for similar work. Fig. 7 shows a compound tube as cut off by the tool. The tool jaws 4, 5 carry two or more parallel.blades 8, 9 with curved cutting-edges of different radius and spaced apart as shown.

Granted: 1900-03-31
Abstract: 22,352. Kimman, H. J. Nov. 8. Steam and other fluidpressure hammers. - Relates to pneumatic percussive tools for hand or other use for riveting, caulking, chipping, &c. and to improvements on the invention described in Specification No. 9239, A.D. 1899, [Abridgment Class Band tools &c.]. The throttle valve H has a stem h acted on by the trigger I, and slides in the bushing G, G<1>, made in two parts, of which the part G' can be screwed upon the part G by the milled head g<2>. The extent to which the openings g<1> are uncovered by the head H when the trigger is pressed full down can therefore be varied, and hence the supply of air which passes through the passages f, g, g<1>, f<1> can be varied also. The valve is pressed back by the spring h<1> and compressed air admitted to the spring chamber by a longitudinal hole in the head H. The valve E oscillates in the bushing E<1>, firmly fixed by a screw cap e<2> or otherwise in the base of the tool. The cylinder A is recessed in the base, and held therein by the screwed sleeve K. During the forward movement of the piston air enters at e<1> and is exhausted at a', and during the backward movement air enters at a<3> and is exhausted at a'. The opening a<3> communicates with the space e<3>, and the channel a' with the channel a<6> through the openings e<4> in the valve. The valve is shifted by alterations of pressure in the channel a<2>, which is provided with openings a<5>, a<10> alternately communicating with the space b<1>, openings a<1> and a<6> in the cylinder being in constant communication with the live air and the exhaust respectively.
Patent GB-190001858-A (GB)
Title: Improvements in Apparatus for Lifting, Transporting, and Lowering Machinery and other Weighty Aricles; specially applicable to Raising Heavy Weights out of and Lowering them into Ships in Dry-dock.
Inventor: WILLIAMSON ROBERT
Filed: 1900-01-30
Granted: 1900-12-01
Abstract: 1858. Williamison, R. Jan. 30. Cranes.-An arm or rib d, built up of two I- section girders, is mounted to rotate on the top of a travelling frame a. The engine and lifting - gear are mounted on one end of this arm d, so as to balance it and the load. The carriage f from which the lifting-block depends is operated in the usual way. When the crane is in use, say to load a ship, the load is raised when the carriage f is close in. The arm d is then rotated to bring it over the ship, and a Y-prop s is then placed below the outer end of the arm d, after which the carriage f can be run out and the load lowered. When used on a railway, a truck on parallel rails may replace the prop s.
Patent GB-190005318-A (GB)
Title: Improvements in Means for Cutting and Expanding Boiler Tubes or the like.
Inventor: MACKENZIE JOHN
Filed: 1900-03-20
Granted: 1900-05-26
Abstract: 5318. Mackenzie, J. March 20. Tube expanders.-Relates to a flue or tube cutter, which may also be used as a tube expander by substituting a roller for the cutting-disc. The tool spindle G is driven by a suitable portable reversing-motor A, and is slotted to receive a taper mandrel 0, which is moved longitudinally to feed the tool R radially. The tool is carried in a block Q, the travel of which is limited by a pin c. The mandrel enters between the block Q and antifriction rollers P, and is traversed by a nut H on the spindle G. Arms I on the nut engage guides J on the motor and prevent the nut from rotating. A disc S, having a ball race d, is held against lock nuts T, U by a cap V, and prevents friction between the nuts T, U, which limit the depth of insertion of the tool, and the tube-plate. The spindle is inserted in the tube, and the motor is started to rotate and feed the tool to a sufficient radial depth, when the motor is reversed till the tool and spindle can be withdrawn.

Title: Improvements in Electric Measuring Instruments.
Inventor: HONIG ARTHUR
Filed: 1900-08-22
Granted: 1901-07-27
Abstract: 15,001. Honig, A. Aug. 22. Current meters.- A continuouscurrent am-meter or volt-meter, shown in Figs. 1 and 2, consists of an axle C carrying a pointer D and controlled by gravity or a spring, and also carrying a ring - shaped per - manent magnet A with a small air-gap at one side ; stationary current conductors are situated in the gap so that the magnet poles move across them when the axle turns. The conductors are part of a coil of wire wound in a former B, which has a flat portion situated in the gap. Such a volt-meter for use on supply feeders may be wound with double wire, one wire being connected between the feeders, and the other to the ends of a main resistance, so as to reduce the effect of the first wire and compensate for the drop in pressure on the feeders. An am-meter for large current may have a conducting- strip E of the form shown in plan in Fig. 7, instead of a coil, a part H of the strip beiog bent into a vertical plane, near the axle C ; this strip may be shunted by the main conductor G, an insulator being interposed at F. By making the coil or conducting-strip of varying thickness in the air-gap, any desired scale can be produced. In a portable instrument, the former in which a pressure-measuring coil is wound may serve as a conductor for current to be measured, or the pressure coil may be supported on a current conducting-strip.

Granted: 1902-03-27
Abstract: 26,061. Imray, 0., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Dec. 20. Dyes, artificial.-Indoxyl and its homologues are produced by heating an aromatic compound containing in the molecule once or more the group (where R means phenyl, tolyl, xylyl, or the like), at a high temperature with an inorganic substance capable of decomposing water, such as alkali metals and their alloys, alkaline-earth metals, alkali amides, alkali nitrides, and metallic carbides. The aromatic compounds mentioned are phenylglycine and its homologues, and their salts, esters, amides, and anhydrides ; phenylglycinylphenylglycine and its homologues, and their salts, esters, and amides ; and alpha-phenylhydantoin and dipenylhydantoin and their homologues. The action of alkali amides on phenylglycine and its homologues is disclaimed. It is advantageous to use a flux such as an alkali cyanide or a molecular mixture of caustic soda and potash. The cooled mass is dissolved in water out of contact with air, then filtered, and worked up into indoxyl, or indigo, in the known ways. Examples of mixtures are given in which (1) a molecular mixture of caustic potash and soda is used with sodium, magnesium nitride, and calcium carbide, respectively ; (2) potassium cyanide is used with sodium amide ; and (3) an alloy of sodium and lead is employed.
